Text to Speech — lifelike AI speech

TKCORE AI Text to Speech turns scripts into listenable audio in one studio flow. Paste up to 600 characters per request, choose a voice and language, adjust speaking rate, pick an export format (MP3, WAV, Opus, Ogg), and optionally describe delivery in plain language with Instruct style controls. Play inline, download, or revisit clips from this session’s history — saved to your account when signed in.

The studio is built for narration, product explainers, accessibility reads, and quick voice drafts without juggling separate demo tabs. Sign in to synthesize audio and load paginated history from your account API.

• Script composer — paste narration or dialogue with a live character counter (max 600 per run).
• Voice picker — built-in Bailian / Qwen timbre presets, site default voice, or a custom provider voice id.
• Language control — Auto or explicit language tags (English, German, Japanese, and more) for clearer pronunciation.
• Speaking rate — slower, normal, faster, or fast segments without editing the script.
• Instruct style panel — presets (news, storytelling, promo) plus free-form delivery notes merged with rate hints.
• Export formats — MP3, WAV, Opus, Ogg downloads from the player when synthesis succeeds.
• Dual history — this-browser session list plus account saves with pagination when signed in.

• Product & tutorial voiceovers — draft narration before booking a human studio session.
• Accessibility & proof listening — hear blog posts, emails, or UI copy aloud for clarity checks.
• Multilingual previews — compare how the same script sounds across language settings.
• Podcast & social clips — quick reads for intros, hooks, or ad spots with style instructions.

Problems it helps solve: “I need to hear this script before publishing,” or “my team wants consistent voice settings without exporting to a separate TTS app.” Value: one URL with voice, language, rate, format, and optional instruct text — then immediate playback and download in the same panel.

Quick workflow

1. Paste your script — use punctuation so pacing feels natural; try Try sample for a starter line.
2. Pick voice & language — choose a preset timbre or enter a custom voice id; set language unless Auto is enough.
3. Tune delivery — optional Instruct presets or your own style notes; pick speaking rate and output format.
4. Generate speech — keep the tab open while synthesis runs; play from the History player or download the clip.

Tips for cleaner audio

• Break long sentences with commas or periods — models pace better on structured text.
• Spell out abbreviations and numbers when pronunciation matters.
• Use Instruct for emotion (“warm tutorial tone”) instead of ALL CAPS in the script.
• Match language setting to the script language for multilingual content.

Example: a product marketer pastes a 400-character teaser, selects a clear English timbre, applies the Promo / ad Instruct preset, exports MP3, and downloads from the player. They regenerate with a slower rate for the landing-page version and compare both clips in session History.
